Foxwell NT604 Elite

Buy the Foxwell NT604 Elite if you specifically need four-system code reading, engine, ABS, SRS, and transmission, with live data, at an entry-level price. Skip it if you’re expecting service reset functions, Foxwell’s own documentation is explicit that oil reset, battery registration, ABS bleeding, throttle body relearn, and ABS relearn are not supported on this model.

The short version: Foxwell’s own product page and the Amazon listing agree closely, this is a focused four-system code reader with live data, not a service-reset or bidirectional tool. Know that scope going in and it’s a solid, honestly-positioned entry-level pick.

What the NT604 Elite Actually Does

Foxwell’s own product page confirms a 4.3-inch color screen handheld scanner supporting all OBD-II protocols, KWP2000, J1850 VPW, ISO9141, J1850 PWM, and CAN, covering 1996-and-newer US vehicles, 2000-and-newer EU and Asian vehicles, light trucks, and SUVs. The tool connects via wired USB and reads and clears codes across four specific systems: engine, ABS, SRS, and transmission, with real-time live data monitoring and a built-in DTC library that explains error codes without needing to look them up separately.

Foxwell’s page is direct about what this model does not do: no oil reset, no battery registration, no ABS bleeding, no throttle body relearn, and no ABS relearn. This isn’t a gap in the documentation, it’s a stated limitation, the NT604 Elite is positioned as a code-reading and live-data tool for these four systems, not a service-reset scanner.

What Amazon Says vs. What Foxwell Confirms

Amazon’s listing for the NT604 Elite describes a check-engine code reader with ABS, SRS, and transmission diagnostics, live data, and airbag light reset capability. [Amazon]

Foxwell’s own product page independently confirms the four-system code reading and live data, matching Amazon’s description. [Foxwell] Both sources are consistent that this is a code-reading tool for these four systems, neither claims service resets, bidirectional control, or ECU coding, this is an honestly-scoped entry-level product on both sides rather than a gap between marketing and documentation. [Amazon] [Foxwell]

What this means for you: four-system code reading and live data are confirmed consistently by both Foxwell and Amazon, safe to rely on for that specific scope. Neither source oversells service-reset or bidirectional capability this model doesn’t have, a straightforward, honestly-positioned entry-level tool.

Four Systems, Not All-System, Not Bidirectional

The “4 System” naming in Foxwell’s own branding is worth taking literally. This scanner reads and clears codes for engine, ABS, SRS, and transmission specifically, not every module a modern vehicle has, and it doesn’t send commands back to components the way a bidirectional scanner does. If your work needs broader system coverage or service resets, Foxwell’s own NT809BT confirms vehicle-wide bidirectional control and 30+ reset functions, at a meaningfully higher price that reflects the real capability difference.

Who This Scanner Actually Fits

The NT604 Elite fits a DIYer or shop that specifically needs engine, ABS, SRS, and transmission code reading with live data, at an entry-level price, and doesn’t need service resets or bidirectional control. It’s not enough tool if your work regularly requires oil resets, ABS bleeding, or other service functions, Foxwell itself is explicit those aren’t included here.

Important Limitations

No service reset functions, confirmed absent by Foxwell: no oil reset, no battery registration, no ABS bleeding, no throttle body relearn, no ABS relearn. No bidirectional control. Wired USB connection only, no wireless confirmed. Limited to four systems, engine, ABS, SRS, and transmission, not an all-system scanner.

Choose It, Skip It, or Consider Something Else

Choose the NT604 Elite if you specifically need engine, ABS, SRS, and transmission code reading with live data at an entry-level price, and don’t need service resets or bidirectional control.

Skip it if service reset functions like oil reset or ABS bleeding matter to your work, Foxwell explicitly excludes them from this model.

Consider the Foxwell NT809BT instead if you need vehicle-wide bidirectional control and a broad service reset list from the same manufacturer, at a meaningfully higher price that reflects the real capability gap.

Our Verdict

The NT604 Elite earns its place as an honestly-scoped, entry-level four-system code reader, Foxwell is explicit about what it does and doesn’t do, engine, ABS, SRS, and transmission code reading with live data, no service resets, no bidirectional control. If your work stays within that scope, it’s a solid, low-cost pick; if it grows to include service resets or active testing, Foxwell’s own NT809BT is the confirmed step up.

Frequently Asked Questions

Does the NT604 Elite support oil reset or other service functions?

No. Foxwell’s own product page explicitly states this model does not support oil reset, battery registration, ABS bleeding, throttle body relearn, or ABS relearn.

Does the NT604 Elite support bidirectional control?

No, neither Foxwell’s page nor the Amazon listing claims bidirectional control for this model. Consider the Foxwell NT809BT if you need that.

Is the NT604 Elite compatible with my specific vehicle?

Our data confirms it against a range of makes and generations in SCG’s database, but exact coverage depends on your specific year, make, and model. Use the Finder to check your vehicle directly.
